3、epartment of Defense.1.Scope*1.1 This specification covers cold-drawn steel wire,as-drawn or galvanized,to be used as such,or in fabricated form,for the reinforcement of concrete,in sizes not less than 2.03mm 0.080 in.nominal diameter.1.2 Supplement S1 describes high-strength wire,whichshall be furn
4、ished when specifically ordered.It shall bepermissible to furnish high-strength wire in place of regularwire if mutually agreed to by the purchaser and the manufac-turer.1.3 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach sys
5、tem may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.(The inch-pound units are shown in bracketsexcept in Table 6.)2.Referenced Documents2.1 ASTM Standards:2A 185/A 185M Spec
